I too have BRP and this is by far the worse year for me. (I have the problem for 13 years) I did a lot of sunbathing this summer as the weather was beautiful. I paid a high price as both arms were very bad. My GP put me on tablets and they work 90% of the time ( anitriptyline 10mg two to be taken at night) at night before bed they can start itching and a quick placing of ice on the itchy area makes it better in a few minutes. I apply three times a day a cream called BOTANICA NATURAL HERBAL CREAM. I order it on line (www.botanica.ie) because the pharmacy I used has closed down. I also find covering my arms help as it seems to be photo sensitive. If I can be of any help do contact me.
